Solder & Low-Melting Alloy Antimonial Lead 6% Sb vs B23 Grade 16
Solder & Low-Melting Alloy · grade comparison
Solder & Low-Melting Alloy Antimonial Lead 6% Sb and B23 Grade 16 are both solder & low-melting alloy grades. Antimonial Lead 6% Sb is the stronger of the two: tensile strength 55 MPa (7.98 ksi) against 45 MPa (6.53 ksi) for B23 Grade 16, about 22% more. Antimonial Lead 6% Sb is the more ductile: elongation 25% versus 2% for B23 Grade 16, and B23 Grade 16 is harder (21 HB vs 14 HB). B23 Grade 16 is lighter (10.1 g/cm³ vs 10.88 g/cm³ for Antimonial Lead 6% Sb) and B23 Grade 16 is stiffer (24 GPa vs 17 GPa). On the shop floor, Antimonial Lead 6% Sb welds better (very good vs not recommended) and Antimonial Lead 6% Sb sits in a lower cost tier (standard, $$) than B23 Grade 16 (premium, $$$).
Antimonial Lead 6% SbChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
B23 Grade 16Choose it when weight is the constraint, or when the part sees heat.
Antimonial Lead 6% Sb vs B23 Grade 16: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all solder & low-melting alloy grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.
